Single‐Layer Optical Platform Based on WDM/TDM Multiple Access for Large‐Scale “Switchless” Networks

Single‐Layer Optical Platform Based on WDM/TDM Multiple Access for Large‐Scale “Switchless” Networks The European Union ACTS project SONATA will define and demonstrate a cswitchlessn all‐optical network to provide a future single‐layer, advanced transport architecture on a national scale. The single‐hop, shared‐access network employs time and wavelength agility (a WDMA/TDMA protocol), using fast tunable transmitters and receivers to route individual customer connections as well as bandwidth pipes through a single wavelength router (suitably replicated for resilience). No electronic switching nodes or cross‐connects (telephony, IP, ATM, SDH) are required within the transport network, nor optical cross‐connects (save the wavelength routing node), thus providing major transport architecture simplifications and hardware reductions.

Abstract

The European Union ACTS project SONATA will define and demonstrate a cswitchlessn all‐optical network to provide a future single‐layer, advanced transport architecture on a national scale. The single‐hop, shared‐access network employs time and wavelength agility (a WDMA/TDMA protocol), using fast tunable transmitters and receivers to route individual customer connections as well as bandwidth pipes through a single wavelength router (suitably replicated for resilience). No electronic switching nodes or cross‐connects (telephony, IP, ATM, SDH) are required within the transport network, nor optical cross‐connects (save the wavelength routing node), thus providing major transport architecture simplifications and hardware reductions. The network is scalable to 200 Tbit/s throughput over 1, 000 krn, connecting 20 million terminals operating at 622 Mbit/s over 50.000‐way split c<hyperPONss, by means of 800 WDM channels with 0.05 nm channel spacing (6.25 GHz). Details of network dimensioning, physical layer modeling and network control issues are presented.
